3 Claims.

This invention relates to improvements in rail anchors.

One object of the invention is to provide a simple and efcient rail anchor which may be readily applied to the rail of a railway track structure and driven along the rail into close engagement with the tie of the railway track and which operates to tightly clamp the rail and positively prevent creeping of the latter with respect to the tie.

A further object of the invention is to provide a device of the character described in the preceding paragraph, of one-piece construction, which may be cheaply and economically manufactured. v

Other objects of the invention will more clearly appear from the description and claims herein-y after following.

In the drawing forming apart of this specification, Figure 1 isa vertical elevational View of a portion of a rail of a track structure showing the tie in vertical section and partly broken away, illustrating my invention Yin connection therewith, the section being substantially on the line Iv-I of Figure 2. Figure 2 is a vertical section on the line 2-,2 of Figure l., the tie being indicated in dotted lines. Figure Bis a top plan view of the structure shown in Figure 1, as viewed from the line 3--3 of said Figure l, in the di: rection indicated by the arrows, thev rail and tie being indicated in dotted lines to more yclearly disclose the structure of the rail anchor which is illustrated in plan.

In said drawing, IS indicates the tie and II one of the rails of a railway track structure.

The rail I I is ofwellfknown type having the usual i base flanges I2-I2 by which it is supported on the ties of the trackstructure.

My improved rail anchor lis of onefpiece con-.-

struction and comprises broadly a base A having a gripping jaw B at one end, an anchoring lug C at the other end, and a laterally outstanding shelf or arm D on the base portion underlying the left hand end and the lug C at the right hand end thereof, as seen in Figure The bottom corners of the section A are preferably .cut away, as indicated at I3 and I4.

The jaw B extends laterally inwardly over the corresponding Vbase flange I2 of the rail as clearly shown in Figure 2, and is connected to the base portion A by a section I5 upstanding from said base portion. The portion of the jaw B which extends over the base flange of the rail, is indicated by I6. As shown in Figures l and 3 the section I5 is bent outwardly away from the tie I8 at an inclination. This is most clearly shown in Figure 3. The section I6 forms an acute angle to the vertical front face of the tie. The jaw B is made of such a length that the free end of the section Iil thereof terminates short of the vertical web of the rail. The bottom edge face of the section fit of the jaw B, which edge face is indicated by I'I, is inclined at a slightly lesser degree than the upper surface of the corresponding base flange I2 of the rail and engages said surface. The portion of the upper edge of the base section AY of the anchor opposed to the lower edge il of the jaw B provides a jaw face I3 which bears on the underside of the rail base. At the inner end of the section I6 of the jaw B, the material of the anchor between the opposed jaw faces I'I and I8 is cut away, Vas shown at I9, to provide clearance vwhen the anchor is in position on the rail, so that there will be no interference with proper positioning of the jaw members on the rail flange. The jaw faces il and i8 of the anchor are preferably so spaced that the jaw Y members will be sprung apart slightly when the anchor is forced onto the rail.

The lug C is in the form of an upstanding lip on the base A and has a vertical inner edge face r2li) adapted to engage with and bear on the outer edge face of the corresponding base flange of the rail. This lug C is preferably of such a height that it engages the majorportion of the Vertical height of the side edge of the rail flange but terminates short. of the top of said Vbase flange.

The shelfV or carin D is in the form stantially ilat tongue `extending laterally from the'top edge of the base section A .of the anchor in a direction away from the tie I0. The shelf D underlies the base of the rail and is in substantially flat iace'engagernent with the under.- neath surface of the rail base. The shelf D is integral with the base portion A of the anchor, being formed by bending said section at an angle to the plane of the base portion A. The material of the upper part of the base portion A immediately adjacent opposite sides of the shelf D is notched out or cut away, as indicated at 2l or 22, to facilitate bending of the plate to form the shelf D, assure contact of the jaw face I8 with the underneath side of the rail base, and provide for proper springing action of the lug C and the shelf D. As shown in Figure 2, the shelf D is located outwardly beyond the free end of the section I of the jaw B and to one side of the vertical plane of the web of the rail II.

The base portion A of the anchor, as shown most clearly in Figure 1, is slightly angularly offset with respect to the upstanding portion of said anchor which forms the jaw B, thereby assuring contact at the lower edge of said base portion with the tie so that a maximum leverage action is obtained to effect clamping of the anchor to the rail.

In applying the improved anchor to the rail the jaw B is first engaged over the outer end portion of the left h'and base flange of the rail, as seen in Figure 2. The lug C will thus contact with the underneath face of the rail base. The anchor is then driven onto the rail flange by applying the driving force to the outer side of the jaw B in a direction toward the rail. Inasmuch as the jaw opening is relatively narrow compared with the tapered base flange of the rail onto which the jaw is driven, the jaw members are forcibly sprung apart by the upper jaw being driven against the slope of the upper face of said rail base ange, thereby producing tight gripping action of the jaw and resultant strong binding of the end of the lug C upwardly against the base of the rail while the anchor is being driven onto the rail flange, and forcibly locking the anchor to the rail when it is driven home, the lug C snapping over the outer edge of the corresponding base flange of the rail as seen in Figure 2. After the anchor has been thus applied to the rail the same is driven along the rail into intimate contact with the vertical face of the tie. As will be evident, the required slippage of the anchor lengthwise on the rail toward the tie is permitted by the arrangement of the shelf D and section i6 of the jaw B which extend in a direction away from the tie. However, relative movement of the anchor and rail in a reverse direction is effectively prevented by the gripping or clamping action of the gripping portions of the anchor, which anchor is buttressed against the tie, thereby preventing creeping of the rail lengthwise in la direction toward that side of the tie on which the anchor bears.

As will be seen, the free end of the section I 6 of the jaw B will dig into the base flange of the rail and such -digging in or gripping action will be greatly augmented as any force is exerted, tending to move the rail lengthwise toward the tie, due to the fact that bending action of the jaw I toward the tie will tend to straighten out said jaw, thereby forcing the free end thereof to ride further up the slope of the flange o-f the rail base with resultant increasing wedging action. At the same time the free edge of the shelf D will bind on the underneath face of the rail base due to the tendency of the base member A of the anchor to rock slightly about its lower edge in a direction toward the vertical front face of the tie.

In addition the shelf D maintains the anchor positioned so that the gripping jaw B thereof will function properly.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

I claim:

2. A one p-iece rail anchor including a fiat platelike base member having a j'aw face formed by an edge portion thereof, a fiat, substantially straight, platelike jaw member at one end of said flat platelike base member having a straight jaw portion overlying said jaw face and having the lower edge thereof providing a jaw face opposed t0 and spaced from said jaw face of the base portion, said jaw member being bent at an angle to one side of the plane of said base portion; of a lug at the other end of said base portion having a vertically disposed, straight abutment fl'ace on the inner side thereof; and a horizontal platelike shelf extending laterally from said base portion, said shelf being extended from the side of said baselike plate portion from which said jaw is angled, said shelf being disposed between the jaw face of said base portion and said lug.
